Definitions

  • Roller-bearings are characterized by the known drawback that the rollers therein can move radially in their cage when one of the races is still to be fitted to the bearing, thus making the fitting of this race a particularly difficult operation.
  • This cage consisting of an envelope of cylindrical configuration, without flanges, comprises rectangular apertures permitting the passage of the rollers in rolling contact with the inner and outer races, and is characterized in that the rollers are held in proper relation to the race, i.e., before the second race is fitted to the assembly, by bosses formed by pressing the cage in a transverse direction, these bosses engaging adequate cavities formed centrally of or concentrically to each roller end face.
  • This type of one-piece cage eliminates the drawbacks characterizing hitherto known multiple-element cages or retainers (such as the risk of disassembling during the bearing operation). Furthermore, the cage of this invention is considerably lighter in weight, given an equal mechanical strength.
  • the manufacture of the cages or retainers according to this invention is much simpler and economical than that of conventional cages, from the dual point of view of material and their assembling operation.
  • FIG. 1 is a fragmentary radial section taken across a rollerbearing comprising two lips on its outer race;
  • FIG. 2 is a fragmentary axial view of the roller-bearing of FIG. 1;
  • FIGS. 3a and 3b are comparative fragmentary sections of rollers having different cavities, the sections being taken along a plane tangent to the cage;
  • FIG. 4 illustrates in fragmentary radial section a roller-bearing comprising two fixed lips on the inner race
  • FIG. 5 illustrates in fragmentary perspective view one portion of a roller-bearing to show the relative arrangement of the component elements of the bearing of FIG. I, the inner race being removed for the sake of clarity.
  • an outer race 1 formed with a pair of fixed lips 2 and 3, and an inner race 4 comprises cylindrical rollers 5 disposed between the two races and separated by a cage or retainer 6 consisting of a cylindrical one-piece envelope or stamping 7 formed with spaced rectangular apertures or cells 8 adapted to permit the passage of rollers 5 and separated by distance-pieces 9.
  • a cage or retainer 6 consisting of a cylindrical one-piece envelope or stamping 7 formed with spaced rectangular apertures or cells 8 adapted to permit the passage of rollers 5 and separated by distance-pieces 9.
  • Each roller has formed in its end faces a concentric cavity 10 of frustoconical configuration, adapted to receive a stamped element or boss 11 of the cage 6 which is preferably eccentric in regard to the pitch circle containing the roller axes.
  • This element or boss 11 may also be obtained by appropriately cutting the aperture 8, or by any other means capable of producing the same result.
  • FIGS. 3a and 3b illustrate in section taken along a plane tangent to the cage and perpendicular to the radial plane containing the roller axis the frustoconical configuration 10 (FIG. 3a) and the conical configuration 12 (FIG. 3b) of the cavities formed in the end face of rollers 5.
  • FIG. 4 illustrates a roller-bearing comprising the same cage as in FIG. 1, the inner race 13 being formed with a pair of fixed lips 14 and 15.
  • FIG. 5 is a fragmentary perspective view showing a rollerbearing equipped with the roller cage shown in FIG. 1, the inner race being omitted to afiord a clearer understanding of the arrangement.
  • a cage comprising a one-piece, relatively thin, lightweight, hollow, flangeless, cylindrical envelope having a plurality of spaced rectangular apertures formed therein for the passage of said rollers, and said envelope having inwardly directed bosses projecting into said apertures and engaging said cavities in the rollers, said cage being eccentrically mounted out of the pitch circle containing the roller axes, and said bosses being formed in a direction parallel to the axes of said races in order to retain the rollers in proper position with the flanged race when only one of the bearing races is fitted in the bearing assembly.
